I had a DTC thrown today, P0101 which is a Mass Air value out of range code. I had recently pulled my K&N filter & for a regular clean & re-oil (I have a Vector CAI) and also sprayed my MAF with some MAF cleaner. I thought maybe that I had used too much oil on re-oiling my K&N filter so I pulled the MAF and cleaned it again & cleared my DTC using my DashHawk. The DTC is gone, but now the idle is surging 300-600 RPMs above normal. Any ideas? Can someone with a CAI kit and the ability to monitor Mass Air flow (via Scan tool, DashHawk, etc.) let me know what value it should be at idle. I am showing 16-18 g/s??? Just wondering if my MAF sensor is shot or what?

I kinda sounds like a leak after the maf, I would go through all the conections after the maf and make sure theres no leaks. when you reinstalled the maf, did you install it going the right direction?

Yeah, thanks Steve. I am actually going to be to see Kirk later this afternoon. I swapped the MAF out and it didn't correct the issue at all. Triple checked to make sure there was no leaks in any of the CAI kit plumbing. I think it might be my TPS sensor that has gone bad in my throttle body, it also threw a P0507 (IAC valve duty cycle high DTC). Hopefuully once Kirk hooks it to his laptop, we'll see exactly what the issue is.

... are you new to Vector?
